WiFi connection issues

Ok this has been going on for a long time. 1.. I cannot get signal on my phone in the bedroom since I've been with you 4years ago.. inserted a booster and still nothing 2 my WiFi in my living room (the connection to power my tv) seems to b a few seconds behind?? I was watching darts last night and as he was throwing the darts the caller was calling out the score just before the arrows hit the board.. its very frustrating and tried a few things but nothing seems to fix it
